Re: Iterate problem

[Mark Lowe]

Well you know what you want to which is most the way there..

You'll want to check the struts docs on indexed properties.

..ActionForm

private ArrayList userList;

public ArrayList getUsers() {
return userList;
}
public addUser(User user) {
this.userList.add(user);
}
...





...

Hi,

I hava a userForm that has a ArrayList of User objects, each User 
object has several properties: fistname, lastname, age.

How can I get all User's firstname, lastname, age in an iterate?

Thanks.

This is all kind of fussy. You have to get the id's and everything 
right, manage the bean names etc, etc, etc.

You can forget all of that stuff and use the nested tags. Makes life 
100% simpler for iterating and everything else.
They've been in Struts since January. Just that not too many people put 
them forward to help the easy stuff, which they make even easier...

Primer, tutorials and downloads...
http://www.keyboardmonkey.com/next

It sounds like a plug, but I've had no complaints from anyone who's 
using them.

Not sure if this is the best way, I'm accomplishing what you are
talking about (using Stores instead of customers) by:

1) I have an action class call some business logic that returns my
collection of Store beans (In your case I would think you would
call the method in the EditCustomerForm that returns to you your
collection of Customer objects).  The action then puts this
collection (in my case ArrayList) into the request (or session).

2) Then in you jsp displaying the info you could do:



   Unit Number: 
   etc


(You might not need the indexId in the iterate tag but I need it
for determining the first time through the list for displaying
certain headers etc. Thanks to those on the list that just showed
me how to do that:)

Hi, Mark:

I am displaying "task" information in an HTML table using the iterate tag.
In the table are a set of input fields that allow my user to modfiy the
values of each task (in your case you may simply want to display the value
as readonly text). By using the "indexed = true" attribute of the "text"
tag, when you submit the html form struts will update each of the action
forms accessible via the getTasks()/setTasks() methods in
"MyTaskActionForm":



 
  

  
  

  
  

  
 


Hope this helps,

Chris

RE: Iterate problem

[Yu, Yanhui]

what we did here is set up a Vector or something like that which holds the
beans (each bean will populate one row in this table).  Then set this Vector
into your session/request depending on what you like, then in the jsp page,
use logic:iterate to create the table rows so the number of table rows will
be the same of number of the elements in the Vector you passed on.

Thanks,

Dear Friends,

I have a jsp in where we have columns as follows

Add no. of rows you wish to add - go

AB   CD  E


save

1. Using java scripts we allow user to add rows
dynamically on the page. 

2. How may I achieve this functionality of dynamically
adding rows using struts? how will it map it back to
an collection attribute in java bean.

Everybody's comments are highly appreciated.

Re: iterate problem

[Oliver Kiessler]

ok. you are right. i created a class "class1" with two properties. in
the action class i create a bean with an arraylist of all class1
objects.

in my view i then iterate thru the arraylist of the bean and display the
two properties of type class1.

works!

thanks, oliver

So are you saying that your two arraylists have to be iterated in parallel?
They have the same number of items and item N from the first arraylist is
associated with item N from the second arraylist?

If so, I'd recommend you create a new bean class containing the two associated
properties, and build a single arraylist of those beans.

Hi Suhas,

No sure what you mean by that...

By the way, do you have to have an array?  If you make it a collection, you can
do away with the index altogether!

You might try Dave Hay's patch that supports indexed properties
directly.

RE: Iterate problem - Any Solutions !!!!!!

[Jon.Ridgway]

Hi Suhas,

I seem to remember a problem with arrays being used in this way. Someone on
this list created some new indexed tags you can grab from Teds site. Not
certain but have a look at:

http://www.husted.com/about/struts/resources.htm#contributions

Specifically have a look at the Indexed Tags:

http://husted.com/about/struts/indexed-tags.htm

Re: Iterate problem

[guido . roth]

Sorry, I'am somewhat at a loss...

I had a similar problem, where it helped composing the property-term to a
variable first, and using double quotes for the property value:

...

<% pVal = view[" + index+ "]"+".orderNo; %>


...

but I never understood why (can anybody tell me?)

Re: Iterate problem

Hi

The parts you show look correct to me. It seems that the problem lies in
the code of method OverDueOrderView.getOrderNo(), which you have not copied
to the mail.

Hi I have a question

My Iterate tag goes like this














<% index++ ;%>

Do I need **IndexId** here as an attribute in the iterate Tag  ??? 'cos In
my form bean when showing the above table there is a call to
 public OverDueOrderView getView(int index) {
  System.out.println(" in side the getView of UpdateOrder Form "+
index);
  return (OverDueOrderView)views.get(index);
 }

Here I'm getting **in side the getView of UpdateOrder Form 0 **  printed
with following error message
 javax.servlet.ServletException: Exception thrown by getter for
view[0].orderNo of bean org.apache.struts.taglib.html.BEAN

What can be the problem -- IS it 'cos i'm not specifying indexId attribute
in the iterate tag or something else ???

Re: iterate problem

[suhas]

if u putting the orderedsandwiches in the session scope in action class ,
then no Need of having  tag in the JSP .

Also instead of keeping that in the session scope in the action class. U can
very well populate the form bean with the contents of that array &
use following in JSP page . Here listOfSandwithces is the array attribute of
the actionForm bean which
